[0023] This embodiment provides a thermal insulation passage 20 for a construction hoist 10 in a severe cold region, which includes a main passage 21, a rolling shutter door 22, a hot air curtain 23, and a monitoring and warning system.

[0024] The main passage 21 is built by a truss frame structure and has an inlet and an outlet that penetrate through opposite ends. The outer wall of the main passage 21 is provided with a thermal insulation material layer 213. The truss frame plays a supporting role for the main passage 21, and the thermal insulation material layer 213 is laid along with the truss, and the laying ensures no gaps to prevent air leakage.

[0025] The rolling shutter door 22 is arranged at the inlet and the outlet for closing the inlet and the outlet. The rolling shutter door 22 has a closing effect on both sides of the main passage 21. During operation, it is necessary to ensure that the two rolling shutter doors 22 on both sides cannot be opened simultaneously. Only when one rolling shutter door 22 is completely closed can the other rolling shutter door 22 be opened. There is a gap between the thermal insulation material layer 213 and the rolling shutter door 22 to ensure that the thermal insulation material layer 213 does not affect the normal operation of the rolling shutter door 22.

[0026] The hot air curtain 23 is arranged at the top of the main passage 21 and is used to blow a row of hot air towards the inlet or the outlet. The main function of the hot air curtain 23 is to prevent cold air from entering the building when the indoor rolling shutter door 22 is opened and can block the entry of cold air.

[0027] Among them, the hot air curtain 23 is an intelligent hot air curtain 23, and the intelligent hot air curtain 23 is configured to autonomously adjust the temperature and power according to the external temperature. When the rolling shutter door 22 is not opened, the hot air curtain 23 operates at the first power, and when the rolling shutter door 22 is opened, the hot air curtain 23 operates at the second power, and the first power is less than the second power. Thus, it can ensure the internal temperature of the thermal insulation passage 20 while achieving the purpose of cost reduction and energy conservation, and then ensure that it does not affect the internal temperature of the building.

[0028] The monitoring and warning system is configured to be able to monitor the internal temperature of the main passage 21, the damage condition of the thermal insulation material layer 213, and whether the hot air curtain 23 trips in real time; when the internal temperature of the main passage 21 is lower than the set requirement, the thermal insulation material layer 213 is damaged, or the hot air curtain 23 is powered off, it will automatically alarm.

[0029] A protective fence 24 is also arranged at a position of the main passage 21 close to the inlet or the outlet, and the height of the protective fence 24 is lower than the height of the main passage 21. The protective fence 24 effectively guarantees the operation safety of construction workers, prevents the rolling shutter door 22 from being opened, and prevents construction workers from accidentally falling, reducing the occurrence of accidents during construction.

[0030] The thermal insulation passage 20 of the construction hoist 10 in cold regions of the present application can allow operators to pass through and transport materials, isolate the indoor and outdoor environments, and has a good effect on maintaining the internal temperature of the building. It can be directly assembled at the construction site, is easy to operate, saves manpower, and increases construction efficiency at the same time; various components can be recycled and reused, saving costs and achieving the goal of green construction. The intelligent hot air curtain 23 can be linked with the rolling shutter door 22 and autonomously adjust according to the sensed external temperature, reducing energy consumption to the greatest extent, ensuring the thermal insulation effect while reducing costs. The layout of the monitoring and warning system facilitates grasping the situation of the thermal insulation passage 20 in a timely manner. When an accident occurs in the thermal insulation passage 20, it can give an early warning to notify the on-site staff in a timely manner.

[0031] This embodiment also provides a setting method for the thermal insulation passage 20 of the construction hoist 10 in cold regions, including the following steps: (1) Determine the truss points according to the opening position, and use the truss to build the framework of the main passage 21.

[0032] The construction hoist 10 will leave openings on the building facade for construction workers and material transportation to pass through. According to the actual opening position on site, determine the position of one end of the truss structure close to the building facade and the width, so as to facilitate the subsequent assembly of the truss structure.

[0033] According to the determined position and size width, erect the truss structure to ensure that the structure is erected firmly and will not be displaced due to accidental impact.

[0034] (2) Install the rolling shutter doors 22 on both sides according to the width of the main passage 21.

[0035] The sizes of the rolling shutter doors 22 on both sides should be determined according to the channel width determined by the opening size. After the rolling shutter doors 22 are installed, there should be no large gaps around the rolling shutter doors 22 to prevent a large amount of cold air from entering the channel through the large gaps, affecting the thermal insulation and airtight effect of the channel. When the thermal insulation passage 20 is working, the rolling shutter doors 22 on both sides cannot be opened synchronously. It should be ensured that when one side is opened, the other side remains closed to ensure the thermal insulation effect.

[0036] (3) Install the hot air curtain 23 on the top of the main passage 21.

[0037] When installing the intelligent hot air curtain 23, the air outlet angle should be controlled so that the air outlet angle of the hot air curtain 23 covers the rolling shutter door 22 on the side close to the building exterior wall to the greatest extent. When the rolling shutter door 22 on the outdoor side is opened and a large amount of cold air rushes into the insulation passage 20, the hot air curtain 23 can play a role in fully convecting the cold air and block the cold air outside the insulation passage 20 to the greatest extent. It can autonomously adjust the air outlet temperature and power according to the external temperature. When the rolling shutter door 22 is opened and closed, the hot air curtain 23 should operate at different powers to maintain the internal temperature of the insulation passage 20 while achieving the purpose of energy conservation.

[0038] (4) Install a monitoring and warning system in the insulation passage 20.

[0039] The monitoring and warning system can be arranged to monitor the internal temperature of the insulation passage 20 and the damage of the insulation material in real time. When the internal temperature of the insulation passage 20 is lower than the set temperature for a long time, the insulation material is damaged, or the hot air curtain 23 trips due to power failure, etc., it will automatically alarm.

[0040] (5) Lay an insulation material layer 213 on the outer wall of the main passage 21.

[0041] The requirement for laying the insulation material layer 213 is that there should be no gaps. The insulation material layer 213 should cover the entire inner circumference of the passage. Note that for the insulation material layer 213 laid parallel to the rolling shutter door 22, there should be an appropriate space left with the rolling shutter door 22 to ensure that the normal operation of the rolling shutter door 22 is not affected.

[0042] (6) Install a protective fence 24 in the main passage 21.

[0043] The protective fence 24 should be firmly connected to the ground. The protective fence 24 is operated in a way that opens towards the building through a limiter. After personnel pass through, the protective fence 24 should be closed in time to ensure the safety of construction personnel and reduce the occurrence of accidents.

[0044] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
